Abstract


The purpose of this research is to study the pretreatment effects of candle nut seed oil on oil yield and its properties. Pretreatments consisted of dry-frying steaming and unpretreatment. The dry-frying was carried out at 100°C for 15 minutes, and steaming was carried out for 30 minutes at the same temperature. Each pretreatment was pressed at 110 kg/cm2 and the difference between means were tested with the LSD procedure.

The results showed that pretreatment gave a highly significant effect on oil yield, specific gravity, saponification number and unsaponifiable matter. It also provided a significant effect on acid number and acid content caloulated as oleic acid. The dry-frying produced the highest of oil yield, a higher specific gravity, and a lower acid number, acid content and unsaponifiable matter based on the oil yield, specific gravity and acid number, the dry-frying method is the best pretreatment compared to the others.
